It's one of the most anticipated films of the year, with its plot being kept heavily under wraps ahead of Friday's release.
But Avengers: Endgame fans are convinced they've figured out one element of the Marvel film's plot, thanks to the red carpet looks of Scarlett Johansson and Brie Larson.
Twitter - Monday - World - Premiere - Fans
Taking to Twitter following Monday's world premiere, many fans pointed out that both actress' sported intricate hand jewellery that mimicked Thanos' famous Infinity Stones, leading many to declare it 'must mean something.'
Scarlett dazzled in a beautiful silver sequinned dress as she attended the star-studded red carpet in Los Angeles, but many fans were distracted by her amazing hand piece.
Black - Widow - Actress - Selection - Rings
The Black Widow actress' selection of six rings were the same as the stones in Thanos' Infinity gauntlet, which of course sparked the famous 'snap' which wiped out half of Earth's living creatures.
Brie also sported similar accessories alongside her beautiful pink silk gown for the event, but instead sported separate rings on her left hand.
Captain - Marvel - Star - Dress - Choice
The Captain Marvel star looked stunning in her dress of choice, and also displayed her choice of jewellery in a stylish social media snap.
Following the red carpet launch, fans took to Twitter in droves to gush about the stars' wardrobe choice.
Fans - Excitement - Stars - Tribute - Franchise
While many fans simply shared their excitement that both stars were paying tribute to the iconic franchise, others theorised that they must have something to do with Endgame's plot.
